01/03/2020 · Moreover, the grindability tests showed that the energy consumption in order to grind a known amount of biocoal sample to the maximum of mm particle size, was almost linearly reduced with increasing the torrefaction temperature. Sabil et al. carried out the torrefaction tests of PKS in the temperatures of 200, 220, 240, 260, 280 and 300 °C. The residence time was fixed at 2 h. The ...
drical agate or sintered corundum grinding elements was used throughout this investigation. This wet·grinding technique uses methyl alcohol as a lubricant to aid mixing and comminution of the sample. A petrological microscope was found to be indispensable for the monitoring of the grain size of the final grind of the sample. Two factors are . SOME PRACTICAL ASPECTS OF QUANTITATIVE XRAY ...
01/01/2020 · Comparative study was conducted on the grindability of wrought GH4169, equiaxial cast K403, directionally solidified cast DZ408 and single crystal DD6 superalloys by using the brown alumina wheels during the creep feed grinding process with regard to the grinding force, grinding ratio, wheel wear and surface integrity.

This paper presents the results of our experimental research on the influence of submicrocrystalline and nanocrystalline sintered corundum abrasives on the grindability of abra¬sive materials containing ceramic glasscrystalline binders, determined in accordance with the first McKeeMoor's indior. Our research was conducted in the conditions of peripheral grinding of sample surfaces made ...
In this study, considering different operational parameters for stirred media mill, change in specific energy was compared to the change in Rx values, the cumulative weight of the material ...
The grindability of Inconel 718 using a corundum and a silicon carbide (SiC) grinding wheel is described in [5]. It was found that the corundum grinding wheel is more effective than the SiC wheel for grinding Inconel 718. The higher grinding temperature leads to a chemical reaction between SiC grit and the workpiece material which causes severe attrition wear. One way to reduce wheel wear is ...

The test results based on the modulus of the corundum phase proved to be inaccurate; thus, a literature value for the Young's modulus E r of the corundum phase of 480 GPa was substituted . The Young's modulus E r of mullite was determined as 161 GPa based on the average value of the tested modulus in the gray area. The Young's modulus of ...
This article presents the results of fly ash from Circulating fluidized Bed Combustion (CFBC) and high temperature fly ash (defined in EN 4501) with modified physical parameters by grinding. For this treatment was used the mechanical mill. In this case were used two fly ashes. The first sample was from Tisová power plant (CFBC fly ash) and the second one from Počerady power plant (high ...
